In Beidou Navigation Satellite System (BDS, etiam quae circumdabit, Chinese Transliteration: Beidou) est global satellite navigation ratio independently developed a Sinis. Est tertia mature satellite navigation system sequentibus GPS et glonass.
Beidou generationem
Frequency Band destinatio beidou generationem et praesertim involves radio determinatio satellite servitium (RDSS) vincula, specie dividitur in uplink et downlink vincula:
a) uplink cohortis: hoc cohortem adhibetur ad user apparatu ad transmittat signa Satellitum, cum frequency range de 1610mhz ad 1626.5MHz, ad quod est ad L-cohortem. Cohors consilio permittit terram apparatu mittere positiones petitiones et pertinet notitia satellitum.
b) Downlink cohortis: Hoc cohortem adhibetur ad Satellitum transmittat signa ad user apparatu, cum frequency range of 2483.5mh ad 2500mhz, ad S-cohortem. Cohors Design Enables satellitibus providere navigation notitia, positioning notitia et alia necessaria ad terram apparatu.
Est notabile quod frequency cohortis destinatio beidou generation ego primarily disposito in occursum technica requisita et positioning accuracy postulat ex illo tempore. Cum technological progressiones et continua upgrades ad beidou system, subsequent generationibus, comprehendo beidou II et III, adoptavit diversis frequency vincula et signum modi modi providere superior-praecisione et certa navigation et positioning servicia.
Beidou generationem II
Beidou Generation II, Second-generation systema de beidou navigation satellite ratio (BDS), est globally accessible satellite navigation ratio independenter developed per Sinis. Building super fundamentum beidou generationem ego, quod fines providere summus praecisione, princeps-reliability positioning, navigation, et leo (Pnt) officia ut users worldwide. Ratio complectitur tres segments: spatio, terra et user. In spatio segmentis includit plures navigation satellitum, in terra segmentum encompasses dominus imperium statio, vigilantia statio, et uplin statio, cum user segmentis complectitur variis accepto cogitationes.
Et frequency Band destinatio beidou generationem II praesertim encompasses tres vincula: B1, B2 et B3, cum propria parametri ut sequitur:
a) B1 cohortis, frequency range of 1561.098MHz ± 2.046MHz, praesertim propter civilian navigation et positioning servicia.
b) B2 cohortis: frequency range of 1207.52MHz ± 2.046MHz, etiam praesertim propter civilian servicia, opus latere ad B1 cohortis providere dual-frequency positioning in capabilities ad amplificata positioning accurate.
c) B3 cohortis: frequency range of 1268.52mhz ± 10.23MHz, praesertim usus ad militarem servicia, offering superior positioning accurate et anti-intercessiones capabilities.
Beidou Generation III
Et tertia-generation beidou navigation ratio, etiam notum quod beidou-III Global navigation Satellite ratio, est globally accessible satellite navigation ratio independently construitur et operatur Sinis. Hoc est effectum saltu a regional ad global coverage, providing summus praecisione, princeps-reliability positioning, navigation, et leo ut users worldwide. Beidou-III offert multiple Open Service signa per B1, B2 et B3 vincula, comprehendo B1i, B1c, B2A, B2B et B3i. Frequentia alias horum annuit ut sequitur:
a) B1 Band: B1i: Center frequency de 1561.098MHz ± 2.046MHz, a basic signum late in variis navigation cogitationes; B1c: Center frequency de 1575.420MHz ± 16MHz, A prima signa supporting beidou-III m / ego satellitibus et sustinuit recentior, summus finem mobile terminals.
b) B2 Band: B2A, Center frequency de 1176.450MHz ± 10.23MHz, etiam a prima signa supporting beidou-III m / ego satellitibus et available in recentior, summus finem mobilis terminals; B2b: Center Frequency de 1207.140MHz ± 10.23MHz, sustineat Beidou-III m / ego satellitibus sed solum available in selectis summus finem mobilis terminals.
C) B3 Band: B3i: Center Frequency of 1268.520MHz ± 10.23MHz, Firmatur ab omnibus satellitibus in utroque beidou generationem II et III, cum excellentia suscipio a multi-modus, multi, frequency modules.
